When the reaction is at  equilibrium  ∴ΔG = Zero 
now we need to get Δ G°, we can get it from this formula:
ΔG° = - RT㏑K(eq)
when we have R = 8.315 J/mol°K and T in Kelvin = 25+273 = 298
so we need to get the K(eq) from this formula:
K(eq) = concentration of products / concentration of reactants
          = [ C] [ D] / [A] [B]
          = (0.8*0.8) / (0.2*0.2) = 16
by substitution in ΔG° formula:
∴ ΔG° = - 8.315 * 298 *㏑(16) = -6870 Jmol^-1 /1000 = - 6.87 KJ mol^-1

How molecular structure affects solubility?
spayn [35]

Answer:

The molecular structure affects solubility mainly biased on its polarity or bonded ions.

Explanation:

Polar molecules will better interact with the water molecules and will dissolve easier. Nonpolar molecules can dissolve if they are small enough, however they don't interact well with the polar molecules. Bonded ions, such as NaCl split into a cation Na and an anion Cl which the positive charge on the Na will be attracted to the oxygen, and the negatively charged Cl will be attracted to the positive Hydrogen.

**Remember this rule, like dissolves like, meaning nonpolar dissolves nonpolar and polar dissolves polar.

I hope this helps!

At what time of the day is most photosynthesis happens
Elodia [21]

I assume that it would be whenever the sun is at it's highest point because it is normally the hottest and covers the most surface area in a place. I'd say like 2pm maybe.

Calculate the mass of 0.0455 mol of Ni
Lera25 [3.4K]

Answer:

2.67g Ni

Explanation:

To convert from moles to mass, use molar mass as a conversion factor.

Nickel has a molar mass of 58.69g/mol.

0.0455mol (\frac{58.69g Ni}{1 mole Ni}) = 2.67g Ni
